PyObjCTools.Signals – Debug signal handling¶
This module is deprecated and will be removed in PyObjC 9.
This module provides two functions that can be useful while investigating random crashes of a PyObjC program. These crashes are often caused by Objective-C style weak references or incorrectly implemented protocols.
This function will install signal handlers that print a stack trace and then re-raise the signal.
Restores the signal handlers to the state they had before the call to dumpStackOnFatalSignal.
This module is not designed to provide fine grained control over signal handling. Nor is it intended to be terribly robust. It may give useful information when your program gets unexpected signals, but it might just as easily cause a crash when such a signal gets in.
